<h1>Building User Interfaces</h1>GWT user interface classes are similar to those in existing UI frameworks
 such as <a href="http://java.sun.com/j2se/1.4.2/docs/api/javax/swing/package-summary.html">
 Swing</a> and <a href="http://www.eclipse.org/swt/">SWT</a> except that
 the widgets are rendered using dynamically-created HTML rather than
 pixel-oriented graphics.
 
 <p>
 While it is possible to manipulate the browser's DOM directly using the
 <a xmlns="" href="com.google.gwt.user.client.DOM.html">DOM</a> interface, it is far easier to use
 classes from the <a href="com.google.gwt.user.client.ui.Widget.html">Widget</a> hierarchy.
 You should rarely, if ever, need to access the DOM directly. Using widgets
 makes it much easier to quickly build interfaces that will work correctly
 on all browsers.
